Although negative symptoms are a barrier to recovery from schizophrenia, little is understood about the psychological processes that reinforce and sustain them. To explore this issue, this study used structural equation modeling to test whether the impact of social withdrawal and emotion recognition deficits upon negative symptoms is mediated by the richness or poverty of personal narratives. The participants were 99 adults with schizophrenia spectrum disorders. Social cognition was assessed using the Bell-Lysaker Emotional Recognition Task; social withdrawal, using the Quality of Life Scale; narrative coherence, using the Scale To Assess Narrative Development; and negative symptoms, using the Positive and Negative Syndrome Scale. The findings reveal that although social cognition deficits and social withdrawal are significantly associated with negative symptom severity, these relationships become nonsignificant when personal narrative integrity is examined as a mediating factor. These results indicate that the development of personal narratives may be directly linked to the severity of negative symptoms; this construct may be a useful target for future interventions.
尽管阴性症状是精神分裂症康复的障碍，但对于强化和维持这些症状的心理过程却知之甚少。为探讨这一问题，本研究采用结构方程模型来检验社交退缩和情绪识别缺陷对阴性症状的影响是否通过个人叙事的丰富或匮乏来介导。研究对象为99名患有精神分裂症谱系障碍的成年人。使用贝尔 - 莱萨克情绪识别任务评估社会认知；使用生活质量量表评估社交退缩；使用叙事发展评估量表评估叙事连贯性；使用阳性和阴性症状量表评估阴性症状。研究结果表明，尽管社会认知缺陷和社交退缩与阴性症状严重程度显著相关，但当将个人叙事完整性作为中介因素进行考察时，这些关系变得不显著。这些结果表明，个人叙事的发展可能与阴性症状的严重程度直接相关；这一构念可能是未来干预的一个有用靶点。
